ALLEN J. SMITH AND JAMES M. WILLIAMS, or VALDOSTA, GEORGIA.

DEVICE FOR LIFTING BOXES FORlIHE REMOVAL OF JOURNAL-BEARINGS.

Specification of Letters Patent.

Patented Apr. so, 1918.

Application filed January 19, 1917. Serial No. 143,380.

To all whom, it may concern:

Be it known that we, ALLEN J. SMITH and JAMES M. VViLLIAMs, citizens of the United States, residing at Valdosta, in the county of Lowndes and State of Georgia, have invented certain new and useful Improvements in Devices for Lifting Boxes for the Removal of Journal-Bearings; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to a new and useful improvement in devices for lifting boxes and bearings off of journals upon axles for the purpose of removing and replacing of journal bearings and making such other repairs as are necessary, displacing the present method of jacks, which have to be placed under the journal box and rest upon crossties or other objects.

The invention consists of a simple and efficient device of this nature having various details of construction, combinations and ar rangements of parts which will be hereinafter fully described, shown inthe accompanying drawings and then specifically defined in the appended claims.

Our invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the device shown as applied to a truck and Wheel of El Citl'.

Fig. 2 is a sectional view on line 22 of Fig. 1.

Fig. 3 is a view in elevation showing a modification of the invention as applied to cars.

Fig. -1- is a sectionalview on line H of Fig. 3.

Reference now being had to the details of the drawings by numerals:

1 designates a car wheel and 2 is an axle. 3 designates a journal box. A plate 4 is provided with an integral boss 5 at one end interiorly threaded for the reception of the jack screw 6 and is provided with an olfset portion 15 conforming to and resting A lug 1% projects from the under surface of said plate and carries a pivotal pin 15 upon which a forked brace 16 is pivotally mounted, the free ends of the latter being adapted to bear against the web of the wheel, in order to securely hold the brace upon the wheel. A collar 19 is securely fitted over the ofi'set end of said plate and carriesin a threaded aperture therein a set screw 18 which is adapted to bear against the upper surface of the plate. Said collar has a downwardly curved finger 17 conforming to the convexed edge of the flange of the Wheel with which it contacts. By this means, the plate, it will be noted, is securely supported upon the wheel. Collars 7 are secured to the jack screwnear its lower end and are spaced apart, one of said collars being, provided with holes 7 for the reception of the boss of a span or wrench. Said screw is swiveled in a boss 9 intermediate said collars and is provided with laterally extending arms 10 to which the hooks 12 are pivotally mounted upon pins 13, upon the arms 10, the said arms being adapted to rest against the arch ing bar 11 of the truck.

In Figs. 3 and at of the drawings we have shown a slight modification of the application of our invention, in which the plate 21 fits over the beam 20 of the truck and rests thereon, said plate being provided with a downwardly projecting flange 22 which engages the face of the beam, while a hook 35, having a sleeve at its upper end, is fitted over a projecting portion of said plate and is held in an adjusted position thereon by means of a set screw 38. The lower end of the hook 35 engages underneath the plate 36. Said plate 21 has an integral boss 24 interiorly threaded for the reception of the jack screw 22 and the lower portion of said jack screw has fixed thereto the collars 27 and 28, between which a boss 26 is positioned and in which the screw is swiveled. In tegral arms 29 of the boss 26 contacts with the pedestal 30, which is adapted to move freely along the side of the oil box. Hooks 32 are pivotally mounted on pins 34: upon the arms 29, and are adapted to engage under the journal box 31. The operation of the form shown in Fig. 1 is as follows: The plate is securely anchored to the top of the wheel with the hook resting underneath the journal box. By turning the screw the box may be lifted in order to remove the worn bearing, the entire weight being thrown upon the wheel. In the form shown in Figs. 3 and 4 of the drawings, the plate carrying the jack screw is supported upon the truck which is rigid and will hold the weight, as the other end of the truck is held by the other two wheels and by this the end with the device on it will lift the weight off the'journal and put the weight upon the truck.

* What we claim to be new is 1. A device for lifting boxes for the removal ofjournal bearings, comprising a plate with an interiorly threaded boss, means for bolting said plate rigidly, a jack screw engaging said threaded boss, a boss having arms fastened to a portion of the truck and in which the lower portion of the jack screw islswiveled, hooks projecting from said arms and adapted to engage underneath the lower edge of a journal box, collars fixed to said screw and adapted to receive means for turning said screw.

.2. A device for lifting boxes for the removal of journal bearings, comprising a plate with an interiorly threaded boss, said plate provided with an offset conforming to and vadapted to fit over the flanged circumference of a wheel, a collar-fitted over the offset end of the plate provided with a curved finger for engagement with the conveXed flange portion of the wheel, a set screw for holding the collar in place upon said plate, a brace pivoted to the plate and having forked ends for engagement with the web of the wheel, a jack screw engaging the threaded boss, a boss in which the lower portion of the jack screw is swiveled and provided with integral arms, a stationary truck frame to which said arms are fastened, collars fixed to the screw upon either sideof the boss in which the screw is swiveled and provided with holes for the reception of means for turning the screw, pins upon said arms, hooks pivotally mounted upon the pins and adapted to engage underneath a journal box.

In testimony whereof we hereunto allix our signatures in presence of two witnesses.
